Ray Allen’s self-expanding tactical deployment mat can be used for stake out and perimeter deployment when the weather is cold or the surface is inhospitable. The mat gives your K-9 partner comfort while waiting to react to a suspect or threat. Simply remove from the carry bag and unfold. The mat will self-inflate. Roll it up again to deflate and store. Storage size is approximately 14 x 10 inches. Once inflated, the mat measures 28 x 40 inches. It’s made of heavy-duty nylon fabric with 1.5-inch-thick foam. A drawstring storage bag is included.
